MySQL date time conversion functions:
Examples:
select name, from_unixtime(time_added, '%Y-%m-%d %h:%i')
from company
order by date_added desc
limit 10; -- list the most recently added companies
You may also omit the '%Y-%m-%d %h:%i' format string, to get the default format YYYY-MM-DD HH:MM:SS, e.g. `2023-09-07 09:43:51`
